Warnings, Cautions and Notices. Note that warnings,

cautions and notices appear at appropriate intervals

throughout this manual. Warnings are provide to alert

installing contractors to potential hazards that could result

in death or personal injury. Cautions are designed to alert

personnel to hazardous situations that could result in

personal injury, while notices indicate a situation that

accidents.

Your personal safety and the proper operation of this

machine depend upon the strict observance of these

precautions.

Read this manual thoroughly before operating or servicing

this unit.

Important

Environmental Concerns!

Scientific research has shown that certain man-made

chemicals can affect the earth’s naturally occurring

stratospheric ozone layer when released to the

atmosphere. In particular, several of the identified

chemicals that may affect the ozone layer are refrigerants

that contain Chlorine, Fluorine and Carbon (CFCs) and

those containing Hydrogen, Chlorine, Fluorine and

Carbon (HCFCs). Not all refrigerants containing these

compounds have the same potential impact to the

environment.Trane advocates the responsible handling of

all refrigerants-including industry replacements for CFCs

such as HCFCs and HFCs.

Responsible Refrigerant Practices!

Trane believes that responsible refrigerant practices are

important to the environment, our customers, and the air

conditioning industry. All technicians who handle

refrigerants must be certified.The Federal Clean Air Act

(Section 608) sets forth the requirements for handling,

reclaiming, recovering and recycling of certain

refrigerants and the equipment that is used in these

service procedures. In addition, some states or

municipalities may have additional requirements that

must also be adhered to for responsible management of

refrigerants. Know the applicable laws and follow them.

ATTENTION: Warnings, Cautions and Notices appear at

appropriate sections throughout this literature. Read

these carefully:

WARNING

Indicates a potentially hazardous

situation which, if not avoided, could

result in death or serious injury.

CAUTIONs

Indicates a potentially hazardous

situation which, if not avoided, could

result in minor or moderate injury. It

could also be used to alert against

unsafe practices.

NOTICE:

Indicates a situation that could result in

equipment or property-damage only

WARNING

Contains Refrigerant!

System contains oil and refrigerant under high

pressure. Recover refrigerant to relieve pressure before

opening the system. See unit nameplate for refrigerant

type. Do not use non-approved refrigerants, refrigerant

substitutes, or refrigerant additives.

Failure to follow proper procedures or the use of non-

approved refrigerants, refrigerant substitutes, or

refrigerant additives could result in death or serious

injury or equipment damage.

WARNING

Proper Field Wiring and Grounding

Required!

All field wiring MUST be performed by qualified

personnel. Improperly installed and grounded field

wiring poses FIRE and ELECTROCUTION hazards.To

avoid these hazards, you MUST follow requirements for

field wiring installation and grounding as described in

NEC and your local/state electrical codes. Failure to

follow code could result in death or serious injury.

WARNING

Personal Protective Equipment (PPE)

Required!

Installing/servicing this unit could result in exposure to

electrical, mechanical and chemical hazards.

• Before installing/servicing this unit, technicians

MUST put on all Personal Protective Equipment (PPE)

recommended for the work being undertaken.

ALWAYS refer to appropriate MSDS sheets and OSHA

guidelines for proper PPE.

• When working with or around hazardous chemicals,

ALWAYS refer to the appropriate MSDS sheets and

OSHA guidelines for information on allowable

personal exposure levels, proper respiratory

protection and handling recommendations.

• If there is a risk of arc or flash, technicians MUST put

on all Personal Protective Equipment (PPE) in

accordance with NFPA 70E or other country-specific

requirements for arc flash protection, PRIOR to

servicing the unit.

strip to provide all necessary terminals for field

connection.The deluxe board is equipped with a random

start relay, anti-short cycle timer, brown out protection,

compressor disable, unit safety control, diagnostics and a

generic relay (which may be available for field use). See

p. 14 for diagnostic information.

Power wiring is made at the contactor.The wiring is fed

through the left or right conduit tube, and into the cabinet’s

control box (contactor).

Schrader Connections

Connections for the low and high side of the refrigeration

system are located conveniently on the chassis’ front

beneath a sheet metal plate.

Sound Attenuation

Sound attenuation is applied as a standard feature in the

product design.The enhanced reduction package includes

a heavy gage base plate, and gasket/insulation around the

compressor enclosure.

An optional deluxe sound reduction package is also

available. It includes a heavy gage base plate, gasket and

insulation around the compressor enclosure, and

vibration isolation between the chassis and cabinet. An

additional dampening treatment is applied around the

compressor enclosure to achieve greater acoustical

reductions.

Unit Description

Before shipment, each unit is leak tested, dehydrated,

charged with refrigerant and run tested for proper control

operation.

Unit Nameplate

The unit nameplate is located at the front of the unit. It

includes the unit model number, serial number, electrical

characteristics, refrigerant charge, and other pertinent unit

data.

Water Connections

½" or ¾" water connections are located on the chassis’s

upper section and clearly labeled for water-in/out hose to

riser hook-up.

Water-to-Refrigerant Coils

The co-axial water-to-refrigerant heat exchanger for the ¾

ton through 3 ton equipment is constructed of copper or

cupro-nickel (option) for the water section and stainless

steel for the refrigeration section.

The heat exchanger is leak tested to assure there is no

cross leakage between the water and refrigerant gas.

ZN510 Controls

Units incorporating the ZN510 control option design will

include a digital LonTalk™ certified control board.The

control board will support such options as: random start

delay, heating/cooling status, occupied/unoccupied mode

and fan/filter status.

Power wiring is made at the contactor.The wiring is fed

through the left or right conduit tube, and into the cabinet’s

control box (contactor). See manual WSHP-IOP-2 for

diagnostic information.

Pre-Installation

Jobsite Inspection

Always perform the following checks before accepting a

unit:

1. Verify that the nameplate data matches the data on the

sales order and bill of lading (including electrical data).

2. Verify that the power supply complies with the unit

nameplate specifications.

3. Visually inspect the exterior of the unit, for signs of

shipping damage. Do not sign the bill of lading

accepting the unit(s) until inspection has been

completed. Check for damage promptly after the

unit(s) are unloaded. Once the bill of lading is signed at

the jobsite, the unit(s) are now the property of the

SOLDTO party and future freight claims MAY NOT be

accepted by the freight company.

4. Verify that the refrigerant charge has been retained

during shipment by use of gauges. Schrader taps are

located external to the cabinet on the ¾-3 ton

equipment.

5. After assuring that charge has been retained, reinstall

the schrader caps to assure that refrigerant leakage

does not occur.

Jobsite Storage

This unit is intended for indoor use only.To protect the unit

from damage due to the elements, and to prevent possible

IAQ contaminant sources from growing, the unit should be

stored indoors. If indoor storage is not possible, the

following provisions for outdoor storage must be met:

1. Place the unit(s) on a dry surface or raise above the

ground to assure adequate air circulation beneath the

unit.

2. Cover the unit(s) with a water proof tarp to protect

them from the elements.

3. Make provisions for continuous venting of the covered

units to prevent moisture from standing on the unit(s)

surfaces. Wet interior unit insulation can become an

amplification site for microbial growth which has been

determined to be a cause of odors and serious health

related indoor air quality problems.

4. Store refrigeration units (chassis) units in the normal

UP orientation to maintain oil in the compressor.

Cabinet configurations may be stored as crated.

5. Do not stack units.

3" SWAGE

Installation

WSHP-SVX10B-EN 13

If unit cabinet assembly includes factory provided risers,

and "no" field provided between-the-floor riser

extensions, please move to Step 1.

Note: Risers are designed to accommodate a maximum

of 1½" to 3" expansion and contraction. If the total

calculated riser expansion exceeds 3", expansion

devices must be field provided.

If unit cabinet assembly includes factory provided risers

and field provided between-the-floor riser extensions are

required, install the extensions before installing the

cabinet.

1. Install drain valve, shut-off/balancing valves, flow

indicators and drain at the base of each supply and

return riser to enable system flushing at start-up,

balancing and service/maintenance.

2. Lift cabinet into space while aligning it into the

3"swage of the riser below.

Note: Take extra care as not to scrape or dent risers

during positioning.The riser should fall

approximately 2" into the 3" swage.This will allow

for the variation in floor-to-floor dimensions, and

keep the riser joints from bottoming out.

3. Level the cabinet.

4. Plumb risers in two planes to assure proper unit

operation and condensate drainage.

5. Anchor all units into place.

6. For field provided risers, center the supply/return

stubouts into the unit expansion slots.The stubouts

should be perpendicular to the cabinet panel.

7. Verify all risers are vertical and that they penetrate the

swaged joint at least 1". Riser should not be allowed to

bottom out.

8. Braze riser joints. Softsolder or low-temperature alloys

should not be used in this application.

9. If risers are field provided, it is recommended that the

risers be anchored to the building structure with a

minimum of one contact point. For expansion and

contraction reasons, do not fasten risers rigidly to the

building.

10. Seal access holes made through the cabinet for piping

with suitable material to help eliminate air leakage.

11. Se e “Cleaning and Flushing the Water Loop,” p. 16 for

system flushing.

Note: Remove shipping straps from risers.

Water Connection

For vibration isolation, it is recommended that flexible

steel braided hoses be installed instead of hard piping

between the vertical risers and the unit chassis.

Trane offers 4-types of hose kit variations:

• Stainless steel braided flexible hose with manual shut-

off (ball) valves

• Stainless steel braided flexible hose with manual

deluxe shut-off (ball) valves

• Stainless steel braided flexible hose with manual

circuit-setter valve

• Stainless steel braided flexible hose with automatic

balancing valve

Additional accessories, such as a strainer are

recommended for use to eliminate contaminants from

entering the co-axial water-to-refrigerant heat exchangers.

Note: Hoses should be no longer than 24”

Field Installed Power Wiring

Verify that the power supply available is compatible with

the unit’s nameplate. Use only copper conductors to

connect the power supply to the unit.

WARNING

Proper Field Wiring and Grounding

Required!

All field wiring MUST be performed by qualified

personnel. Improperly installed and grounded field

wiring poses FIRE and ELECTROCUTION hazards.To

avoid these hazards, you MUST follow requirements for

field wiring installation and grounding as described in

NEC and your local/state electrical codes. Failure to

follow code could result in death or serious injury.

NOTICE:

Use Copper Conductors Only!

Unit terminals are not designed to accept other types of

conductors. Failure to use copper conductors may

result in equipment damage.

Installation

14 WSHP-SVX10B-EN

Main Unit Power Wiring

A field supplied disconnect switch must be installed at or

near the unit in accordance with the National Electric Code

(NEC latest edition).

Location of the applicable electric service entrance for

HIGH (line voltage) may be found in Figure 5, p. 14.

Route power wire to the cabinet control box through the

factory installed conduit at the top of the unit

cabinetry.The high voltage connection is made at the 1PB1

power block in the cabinet control box. Refer to the

customer connection diagram that is shipped with the unit

for specific termination points.

Provide proper grounding for the unit in accordance with

the local and national codes.

Control Power Transformer

The 24V control power transformers are to be used only

with the accessories called out in this manual.

Transformers rated greater than 75 VA are equipped with

internal circuit breakers. If a circuit breaker trips, turn OFF

all power to the unit before attempting to reset it.

The transformer is located in the chassis control box.

Drywall Installation

Before installing drywall around cabinet, cover the cabinet

supply and return openings with plastic or cardboard to

help prevent dust or construction debris from reaching

unit components. Warranties will be voided if paint or

foreign debris is allowed to contaminate internal unit

components.

The location of the drywall may be dependent upon the

type of return air access design.

For units containing a field provided return air access

assembly, the contractor must calculate location of

drywall to allow for frame mounting.

Figure 6. Mock-up of stud placement

1. Locate the side studs a

minimum of 1¼” and a

maximum of 1 3/8” from the

cabinet to the side of the stud.

This critical dimension,

combined with "distance

between studs" is used to

determine the side-to-side

opening for the door, dimension

A.The distances provided in the

table are a "minimum"

dimension. Allow 3½” from the

front of the cabinet to the sheet

rock surface, Figure 7, p. 15 - top

view, Figure 6, p. 14 - mock-up

of stud placement.

Installation

WSHP-SVX10B-EN 15

3. Locate dimensions A and B for sheet rock opening size.

The position of the sheet rock opening must be

centered side-to-side with the return-air opening in the

cabinet. Ensure the bottom of the sheet rock opening is

2¼” below the return-air opening in the cabinet.This

allows the door recess to rest on the bottom of the

sheet rock opening for proper vertical placement of the

door.

4. Place the door frame into the sheet rock opening. A

positive seal is critical between the back of the door

frame and the front of the cabinet. Ensure that the

gasket material seals properly.

Note: When placing the sheet rock panel, make certain

the opening for the door is centered with the

return-air opening in the cabinet (±1/8").

8. Install Filter.

9. Vacuum all dust and construction debris from unit after

cutting out supply/return openings.

Supply Air Ductwork

A 2" (50.8 mm) duct flange may be required to help

eliminate supply air from recirculating back into the return

air, air-to-refrigerant coil prior to discharging into the

space.

Equipment containing a top discharge, ducted design:

install field ductwork to the unit providing a water tight

flexible connector at the unit.This helps prevent operating

sounds from transmitting through the ductwork. Elbows

with turning vanes or splitters are recommended to

minimize air noise due to turbulence and to help reduce

static pressure.

4. Connect water coil pipe to the system riser with a

flexible steel hose assembly.

5. Verify that the shut-off/balancing valve in the return

line/supply line are closed.

6. Place shut-off valves in appropriate location (see

sticker on the equipment for best placement

recommendation) to allow chassis to slide easily in/out

of unit cabinet.

7. Flush system. See “Cleaning and Flushing the Water

Loop,” p. 16,” for flushing instructions.

8. Open the unit water valves and check piping for leaks.

9. Connect electrical to unit chassis via the quick connect

mating plugs.

Note: Four plugs are included (motor, optional

condensate overflow, power and thermostat).

11. Verify unit’s air filter has shipped with the cabinet.

12. Install cabinet’s front cover to the hinged door.

Important: Ensure the gasket material creates a

positive seal around the entire coil to avoid

coil bypass. If a field supplied door is used,

ensure the front cover is attached to the

building structure and not the unit cabinet.

Supply Grille Installation

See Table 5, p. 16 for supply air dimensions.

1. Install the supply grille(s) into the cabinet discharge

opening. Ensure there are no air gaps between the

cabinet supply air and the grille.This helps prevent

recirculation of supply air into the return air opening

behind the drywall.

2. Secure grille(s) into the drywall via two screws.

Cleaning and Flushing the Water Loop

After the piping system is complete, the flexible hose

connectors should be doubled back to complete the water

circuit external to the unit (avoiding trash settle-out in the

condenser). An extra pipe may be necessary to connect

the hose kits. See “Using Antifreeze,” p. 17 for antifreeze/

water mixture by volume.

1. Water circulation system should be filled with clean

water using the water make up connections.

Note: Air vents should be opened during filling.

2. With the air vents closed, start the circulating pump

and then crack the air vents to bleed off the trapped air,

assuring circulation through all components of the

system.

Note: Make up water must be available to the system to

replace the volume formerly occupied by the air

that is bled off.

Note: System water pressure needs to be relieved prior to

opening system.

3. With the air vented and the water circulating, the entire

system should be checked for leaks with repairs made

as required.

4. Operate the supplementary heat system making

checks per manufacturer’s instructions. During this

operation, visual checks should be made for leaks that

required.

5. Open the system at the lowest point for the initial blow

down (making sure the make up water is equal to the

water being dumped). Continue blow down until the

water leaving the drain runs clear, but not less than 2

hours.

6. Shut down pumps and supplementary heat system.

Reconnect the hoses placing the water-to-refrigerant

heat exchanger in the water circulating system.

Note: Vents should be open when the pumps and

supplementary heat system are shut down.

Using Antifreeze

In areas of the country where entering water temperatures

drop below 45°F or where piping is being run through

areas subject to freezing, the loop must be freeze protected

by using an approved antifreeze solution to prevent the

earth loop water from freezing inside the heat exchanger.

Methanol and glycols are the most commonly used

antifreeze solutions. Consult your geothermal unit

supplier for locally approved solutions in your area.

Propylene glycol is not recommended in installations

where the water temperature are expected to fall below

30°F. At extreme temperatures, the viscosity increases to

the point where normal loop circulating pumps may not

maintain proper flow.

If propylene glycol is the only locally approved solution for

anti-freeze, good engineering practices should be used to

achieve the desired flow.

Calculate the approximate volume of water in the system

by using the requirements detailed inTable 8, Water

Volume. Add three gallons to this total to allow for the

water contained in the hose kit and geothermal unit.

Low Voltage Wiring

Factory ordered thermostats and zone sensors are pre-

wired with a quick connecting plug.

1. After installing the cabinet assembly, simply plug the

male portion of thermostat/zone sensor plug into the

female portion of the plug located inside the unit’s

junction box.

2. Mount the thermostat or zone sensor on the finished

drywall.

Thermostat/zone sensor connection is shown in Figure 15,

p. 17.

Low Voltage Wiring for Field Provided

Thermostats/Zone Sensors

Ensure that the AC control wiring between the controls

and the unit’s termination point does not exceed three (3)

ohms/conductor for the length of the run.

Check all loads and conductors for grounds, shorts, and

mis-wiring.

Do not run the AC low voltage wiring in the same conduit

with the high voltage power wiring.
